Inferential control is now considered a good strategy to deal with difficulties in providing on-line measurement for product properties. This paper presents the application of inferential control in fatty acid fractionation column. Here, product compositions are estimated on-line using an empirical model based on Partial Least Square (PLS) regression. A number of refinements to the standard PLS models were introduced to improve both the accuracy and robustness of the estimator. These schemes were evaluated against various process uncertainties including large and frequent disturbances. The results confirmed the superiority of this approach over the usually adopted tray temperature control system.
